Premium 3 High Step

The Premium 3 is our newest iteration of our bestselling Premium line. We kept the beloved folding frame and 20 inch commuter friendly tires but upgraded the electric system to our latest and greatest version and we blew up the tires from 20X2.15 to a full 3 inch tire for better suspension and stability. The smaller frame and weight are why city commuters love to ride this bike.


Can be configured to a Class 1, 2, or 3 E-Bike.

The Battery

The heart of the Premium 3 is the integrated, long-range 48V / 15.6Ah / 749Wh Samsung battery that powers rides up to 50 miles, depending on variables like body and cargo weight, terrain, wind direction, and pedal assist level.
